摘要: Sensitive and selective detection of Hg2+ in solution is a challenging work. An anodic stripping voltammetry with prestripping step at an situ formed bismuth film modified glassy carbon electrode was proposed for mercury(II) solution. This able to decrease the background improve signal-to-noise ratio thus enhance sensitivity. With this method, highly sensitive ppt-level limit 0.5 ng L−1 could be achieved. Moreover, method provides low interference, rapid extreme simple convenience, hold great promise determination.
